OVERVIEWThe NoMax® 1000 and 2000 Series Capacitor Controls utilize user selectable functions andparameters to control switched capacitor banks. The NoMax 1300 controls with time andvoltage, the NoMax 1600 controls with time, temperature and voltage and the NoMax 2000controls with VAR and voltage.

TIME - The Control will close the capacitor bank when the user selected CLOSE TIME occurs.The Control will open the capacitor bank when the user selected OPEN TIME occurs. Bothsettings are subject to the weekend settings.

VOLTAGE - The Control will close the capacitor bank when the sensed line voltage dropsbelow the user selected CLOSE VOLTS setting. The Control will open the capacitor bankwhen the sensed line voltage rises above the user selected OPEN VOLTS setting.

TIME WITH VOLTAGE OVERRIDE - The Control will function according to the time mode,except the time mode operating conditions will be overridden by voltageconditions according to the volt mode function.

TEMPERATURE - For Summer Schedule (defined by CLOSE TEMP greater than OPEN TEMPsetting) - the Control will close the capacitor bank when the sensed ambient temperaturerises above the user selected CLOSE TEMP setting. The Control will open the capacitor bankwhen the sensed ambient temperature drops below the user selected OPEN TEMP setting.

For Winter Schedule (defined by OPEN TEMP greater than CLOSE TEMP setting) - the Controlwill close the capacitor bank when the sensed ambient temperature drops below the userselected CLOSE TEMP setting. The Control will open the capacitor bank when the sensedambient temperature rises above the user selected OPEN TEMP setting.

TIME WITH TEMPERATURE OVERRIDE - The Control will function according to the timemode, except the time mode operating conditions will be overridden by temperatureconditions according to the temp mode function.

TEMPERATURE WITH VOLTAGE OVERRIDE - The Control will function according tothe temp mode, except the temp mode operating conditions will be overridden by voltageconditions according to the volt mode function.

TIME WITH VOLTAGE AND TEMPERATURE OVERRIDE - The Control will function accordingto the time mode, except the time mode operating conditions will be overridden bytemperature conditions according to the temp mode function and/or by voltage conditionsaccording to the volt mode function. Voltage will override both time and temperature.

VAR - The Control will close the capacitor bank when the VAR settings drop below the userselected Amps Reactive setting. The Control will open the capacitor bank when the VARsetting rise above the user selected Amps Reactive setting.

VAR WITH VOLTAGE OVERRIDE - The Control will function according to the VAR settings,except the VAR setting operating conditions will be overridden by voltage conditionsaccording to the volt mode function.

INSTALLATIONAll NoMax Controls are supplied ready for 4 or 6 jaw meter socket mounting or for mount-ing directly to a pole with a supplied mounting bracket. See the Specifications section (pg19) for socket terminal assignments.

WARNING: Before plugging the Control into a live meter socket, rotatethe main switch out of the AUTO/OPERATIONS position or remove thefront panel fuse, and observe all safety procedures for working withexposed live circuits. Failure to comply can result in death, personalinjury or equipment damage.

Socket mounted Controls are supplied ready for either ringed or ringless meter sockets.The two types of sockets are not interchangeable. Be sure that the correct type of Controlis selected for the meter socket to be used.

INSTALLING INTO A RINGED BASEAlign the terminals on the back of the Control and press firmly into the meter socket.Use the supplied ring to complete the installation. Attach a ground wire to the externalground lug. Seal or lock the ring only after the entire system has been verified.

INSTALLING INTO A RINGLESS BASEAlign the terminals on the back of the Control and press firmly into the meter socket. Tightenthe 3 locking screws located on the meter base. Attach a ground wire to the external groundlug. Seal the three locking screws only after the entire system has been verified.

INSTALLING POLE MOUNTED CONTROLSPole Mounted Controls are mounted with the included pole bracket and user suppliedmounting straps or lag screws. After the Control is attached to the pole, attach a groundwire to the external ground lug. The Control should be wired by connecting the 6 wires(must be deenergized during connection) as per the diagrams below. The terminalblocks can accommodate wire sizes from #4 to #18.

Series 1000 Time,Temperature, Voltage Controls Series 2000 VAR Controls

CURRENT SENSORAll NoMax VAR Controls are supplied ready to operate with Lindsey™ CVMI or FisherPierce™ 1301 overhead current sensors, which can be purchased separately. The sensoroutput must be 600A: 10V. If the current sensor is connected to a phase different thanthe Control supply voltage, refer to the software section of this manual (pg 22) to makephase adjustments. The meter socket pin assignments are shown in the Specificationssection of this document (pg 19).

Voltage sensing for the VAR Control is pre-wired to use the supply voltage, typically 120 or240V. Please consult the factory for other configurations.

FUSINGAll NoMax Controls are supplied with a 15 Amp SLO-BLO® fuse, accessible from the frontpanel. This fuse protects the capacitor bank switches. If it was removed before installation,the fuse should be reinstalled after installation is complete.

An internal fuse that is not field replaceable protects the Control circuitry.All repairs should be referred to the factory.

MANUAL OPERATIONAll NoMax Controls can be used to operate the connected capacitor bank switchesmanually. To manually CLOSE or OPEN the capacitor bank using the Control frontpanel toggle switch:

1) Switch the Control out of the AUTO/OPERATIONS mode, verify that the redlamp is off, and select TIME DELAY. Usingthe ADJUST knob, select the desired timedelay, in seconds, from 3 to 600. Thiswill delay both manual and automaticoperations by the time selected. TheOPERATION PENDING light flashesbefore every open or close operationduring the time delay period.

2) Select SWITCH TYPE. Use the ADJUSTknob to select the type of capacitorbank switch installed - MOTOR OP(for motor driven switches) or SOLENOID(for solenoid operated switches).

3) Use the MANUAL toggle switch toOPEN or CLOSE the capacitor bankswitches. The OPERATION PENDINGlight will flash for the duration of theselected TIME DELAY. When theoutput is energized, the CLOSE orOPEN light will flash (100 msec. forSOLENOID or 15 sec. for MOTOR OP).Then, the output will de-energizeand the light will remain on.

The capacitor bank cannot perform aclose operation less than 5 minutesafter a trip operation to allow time forthe capacitors to discharge. If a CLOSEoperation is attempted during this5 minute time period, the Control willdisplay 5MIN DLY and the Control willnot close the bank.

NOTE:Manual operations are counted bythe operations counter (close operationsonly), but manual operations do notcount against the preset daily limit set byMAX OPS/DAY.

After completing the required manual operations, return the Control to AUTO/OPERATIONS for automatic operation. The AUTO/OPERATIONS light confirmsAutomatic operation. The display shows the total number of CLOSE operations.

NOTE: Pending manual operations can be canceled by turning the Control toAUTO/OPERATIONS. Similarly, pending automatic operations can be canceledby switching out of AUTO/OPERATIONS to any other switch position.

PROGRAMMING FOR AUTOMATIC OPERATIONProgramming and set-up information for NoMax Controls.

Settings Common to all ModelsAUTO/OPERATIONS is the normal automatic operating mode for the Control. The displayshows the operations counter, which cannot be reset. The operations counter counts allCLOSE operations.

TIME DELAY sets the time delay, in seconds,for both manual and automatic operations.The delay can be set from 3 to 600 secondsin 3 second increments using the ADJUSTknob. The OPERATION PENDING light flashesbefore every open or close operation duringthe entire time delay period.

MAX OP’S/DAY sets the maximum number ofautomatic capacitor bank CLOSE operationsper rolling 24-hour period. This can be setfrom 2 to 24 operations using the ADJUSTknob. This setting overrides all other time,temperature, VAR or voltage settings. If thedaily operations limit is reached, the displaywill alternately show the operations counterand OP LIMIT while the Control is in AUTO/OPERATIONS mode. When MAX OPS isreached, the last operation will be anOPEN. Manual operations do not countagainst the limit set by MAX OP’S/DAY.

SWITCH TYPE specifies the type ofcapacitor bank switch installed,MOTOR OP or SOLENOID. This settingdetermines the output relay ON time(100 msec. for a SOLENOID operatedswitch and 15 sec. for a MOTORoperated switch).

SETTING THE CONTROL MODEThe Model 1300 Control allows voltageto override time settings. Override meansthat voltage and/or temperature will takeprecedence over time. The Model 1600Control can allow voltage and/or temperatureto override time settings. The Model 2000Control can allow voltage to override VARsettings. Depending on the Model, thefollowing Control Modes can be used:

Control DisplayMode ShowsTime only TIMETime with voltage override VOLT/TIMVoltage only VOLTTime with temperature override TMP/TIMETemperature only TEMPTemperature with voltage override VOLT/TMPTime with voltage and V/TMP/TI

temperature overrideVAR only VARVAR with voltage override VOLT/VAR

SCHEDULE SETTINGS FOR MODELS 1300 AND 1600Four independent time schedules are available - SCHEDULE 1 through SCHEDULE 4. Eachtime schedule allows one OPEN and one CLOSE operation per day. The four time schedulescan be used to set multiple OPEN and CLOSE operations for each day or they can be usedfor seasonal changes to the time schedule, e.g. different OPEN and CLOSE times forsummer and winter. For those units so equipped, the different time schedules can alsobe used for daily or seasonal variations in voltage or temperature override settings.

For each schedule selected, week days MON-FRI,weekend days SAT and SUN, and HOLIDAYS canbe selected to be ACTIVE or OFF. ACTIVE days willfollow the TIME ON and TIME OFF settings as wellas any temperature or voltage override settings. OFFdays will cause the capacitor bank to remain open.

The six standard holidays are New Years Day,Memorial Day, July 4th, Labor Day, ThanksgivingDay and Christmas Day. The NoMax 1600 allowsa maximum of ten holidays to be programmed.

EXAMPLE 1 - SEASONAL VARIATION - Two time schedules are used for seasonal variationin the OPEN and CLOSE times and/or override settings (if any). TIME SCHEDULE 1 is asummer schedule with a START DATE of 4/1, a STOP DATE of 9/30, TIME ON at 07:00and TIME OFF at 18:00 (all time settings are in 24 hour format). TIME SCHEDULE 2 is awinter schedule with a START DATE of 10/1, a STOP DATE of 3/31, TIME ON at 08:00 andTIME OFF at 16:00. For each time schedule, the days of the week, TIME ON, TIME OFFand override settings (if any) can be set independently.

In this example, each schedule is ACTIVE for all days of the week and holidays and sched-ules 3 and 4 are not used. The CONTROL MODE is set for TIME, so voltage and temperaturesettings are not used.

To disable a time schedule, set the start date the same as the stop date. To make aschedule run year round, set the start date for 01/01 and the stop date for 12/31. Incase of a conflict between time schedules, SCHEDULE 1 takes priority over SCHEDULE2, SCHEDULE 2 over SCHEDULE 3, etc. In case of a conflict between temperature andvoltage settings, voltage takes priority. To make a time schedule active for 24 hours,set TIME ON the same as TIME OFF.

EXAMPLE 2 - TIME WITH VOLTAGE OVERRIDE - Two time schedules are used foryear-round time and voltage control. SCHEDULE 1 is a weekday schedule for time withvoltage override. Set the CONTROL MODE for VOLT/TIME (time with voltage override).The TIME ON is 08:00 and the TIME OFF is 18:00. Set MON-FRI to ACTIVE and set SAT,SUN and HOLIDAYS to OFF. The START DATE is 1/1 and the STOP DATE is 12/31.

The Control will anticipate voltage changes caused by opening and closing the capacitorbank. This may cause scheduled open or close operations to be deferred or delayed.See the Voltage Settings section (pg 12) for more information about Adaptive Trip.

IMPORTANT!Time with voltage override means that voltage takes precedence. For theseSCHEDULE 1 settings, the Control will close the bank at 08:00 only if the line voltage isbelow the OPEN VOLTS setting less the Adaptive Trip bias voltage. Conversely, the Controlwill open the bank at 18:00 only if the line voltage is above the CLOSE VOLTS setting plusthe Adaptive Trip bias voltage. If the Control does not close the bank at the TIME ONsetting or open the bank at the TIME OFF setting due to voltage conditions, it will open orclose the bank later if the line voltage changes. The Control will also close the bank beforethe scheduled time of 08:00 if the line voltage drops below the CLOSE VOLTS setting.

SCHEDULE 2 is a weekend schedule for voltage control only. Set the CONTROL MODE forVOLT (voltage control). For 24-hour control, set the TIME ON and TIME OFF to the sametime. Set MON-FRI to OFF and SAT, SUN and HOLIDAYS to ACTIVE. Set the START DATE to1/1 and the STOP DATE to 12/31. The Control will change from a weekday to a weekendschedule at midnight.

If 24-hour voltage control is not desired, the TIME ON and TIME OFF settings can be setas needed. The Control will close the bank at TIME ON only if the line voltage is below theOPEN VOLTS setting less the Adaptive Trip bias voltage. The Control will open the bank atTIME OFF independent of voltage.

EXAMPLE 3 - TIME WITH TEMPERATURE AND VOLTAGE OVERRIDE - Two timeschedules are used for seasonal variations in temperature and voltage override settings.

SCHEDULE 1 is set for TEMP/TIME (time with temperature override) using the CONTROLMODE setting. This is a daily summer schedule so the START DATE is 4/1 and the STOPDATE is 9/30. The TIME ON is 08:00 and the TIME OFF is 18:00. The OPEN TEMP is 60°Fand the CLOSE TEMP is 80°F. MON-FRI SAT, SUN and HOLIDAYS are all set to ACTIVE.

IMPORTANT!Time with temperature override means that temperature takes precedence.For these SCHEDULE 1 settings, the Control will close the bank at 08:00 only if thetemperature is above the OPEN TEMP setting of 60°F. Conversely, the Control willopen the bank at 18:00 only if the temperature is below the CLOSE TEMP setting of80°F. If the Control does not close the bank at the TIME ON setting or open the bankat the TIME OFF setting due to temperature conditions, it will open or close the bankwhen the temperature changes. The Control will also close the bank before thescheduled time of 08:00 if the temperature increases above the CLOSE TEMP setting.

SCHEDULE 2 is set for VOLT/TIME using the CONTROL MODE setting. This is the winterschedule so the START DATE is 10/l and the STOP DATE is 3/31. The TIME ON is 08:00and the TIME OFF is 18:00 MON-FRI, SAT, SUN and HOLIDAYS are all set to ACTIVE.Voltage settings are set as needed.

OTHER SETTINGSBesides the four independent time schedules, there are three other time settingsto be entered. DAYLIGHT SAVINGS can be set to ACTIVE or OFF. Selecting ACTIVEautomatically adjusts the internal clock and all time settings for daylight savingstime in the spring and fall. Selecting OFF causes the Control to ignore daylightsavings time changes.

SET TIME and SET DATE are used only for initial set-up of the Control, or after thebattery has been replaced. The time is entered in 24 hr. format and manually adjustedin 5-minute increments. The date is entered as mm-dd-yy. [The first day in the year2000 will be displayed as 1/1/00]. Reference the software for setting the date and time.

Voltage Settings - All ModelsOPEN VOLTS must be at least 3 volts above CLOSE VOLTS and cannot be set to anyvoltage difference less than 3 volts. The control voltage is measured and averagedover a 5-minute period to reject momentary spikes or sags. The Control will notrespond to short-term voltage changes such as those caused by a sudden linevoltage change or adjusting the control voltage with a variable transformer.

Voltage Controls also incorporate Adaptive Trip; the Controls are sensitive to thevoltage rise caused by closing the capacitor bank. The voltage rise caused by closingthe capacitor bank is averaged over the last 4 close operations and is used to anticipatethe voltage change for the next close or open operation. This voltage change is usedas a bias, and if the next close operation would cause the Control voltage to be abovethe open voltage set-point, the close operation is not performed until the voltagefalls below the open voltage set point less the bias voltage. Similarly, if the next openoperation would cause the Control voltage to be below the close voltage set point,the operation is not performed until the voltage rises above the close voltage setpoint plus the bias voltage. The initial factory default bias setting is 2 volts.

Temperature Settings - Model 1600OPEN TEMP cannot be set closer than 5°F above or below CLOSE TEMP. OPEN TEMPcan be either higher or lower than CLOSE TEMP for summer or winter peaking loads.Temperature is measured and averaged over a 30 minute period so the Control willbetter respond to temperature sensitive VAR loading. The Control will not respondto short-term temperature changes such as those caused by spraying cold water onthe temperature sensor.

13

VAR SETTINGS - MODEL 2000To simplify settings, voltage has been factored out of the VAR settings leaving onlyAmps Reactive - A REAC - on the front panel. When setting Amps Reactive open orclose, the display will also show LD for Leading or LG for Lagging. Amps Reactive Openmay be set up to 100 Amps Leading. Amps Reactive Close can only be set lagging andmust be at least 2 amps more lagging than Amps Reactive Open. Amps Reactive CloseRange is LG 600 to LD 0.5.

The Amps Reactive are measured and averaged over a 5-minute period to reject mo-mentary transients. The VAR settings also incorporate Adaptive Trip; the Controls aresensitive to the change in reactive amps caused by closing and opening the capacitorbank. The change in reactive amps caused by closing the capacitor bank is averagedover the last 4 close operations and is used to anticipate the change in reactive ampscaused by the next close or open operation. This change is used as a bias. If the nextclose or open operation will place the Control beyond the next reactive amps setpoint, that operation is not performed until the reactive amps changes beyond the setreactive amps plus the bias. The initial factory default bias setting is 10 amps reactive.

REVERSE POWER SET sets the action of the Control when reverse power flow isdetected. Options are: IGNORE - to do nothing and leave the capacitor bank in itspresent state, VOLT - to revert to voltage control, or OPEN - to open the capacitorbank until normal power flow is restored.

EXAMPLE - VAR WITH VOLTAGE OVERRIDE - The VAR Control does not use timeschedules so all settings are active at all times. The CONTROL MODE is set to VOLT/VAR,for VAR with voltage override. That is, the Control will follow the VAR settings unlessthe voltage is outside of the voltage set points. The VAR settings are set as follows:A REAC OPEN (Amps Reactive Open) is LD 5.0 (5 Amps leading). A REAC CLOSE(Amps Reactive Close) is LG 50.0 (50 Amps lagging). Voltage Override settings are setto VOLTS OPEN 128.5 and VOLTS CLOSE 122.0. The Control will open the bank, regardlessof VARs, if the control voltage exceeds 128.5V. The Control will close the bank, regardlessof VARs, if the control voltage falls below 122.0V.

IMPORTANT! The Control may not operate exactly at the above set points due to theAdaptive Trip feature described earlier. For example, the Control may not close at theA REAC CLOSE set point of LG 50.0 if doing so would raise the control voltage abovethe VOLTS OPEN set point of 128.5V. Similarly, the Control may not open the bank atthe A REAC OPEN set point of LD 5.0 if doing so would lower the control voltage belowthe VOLTS CLOSE set point of 122.0V. Any operation that is deferred due to AdaptiveTrip will take place as VAR or voltage conditions change.

SYSTEM MONITORINGDepending on the Model, the actual line voltage,ambient temperature or VARs can be monitoredusing the MONITOR settings. This can be helpfulfor setting up and checking Control operation.All parameters are measured and displayedreal-time without any time delay or averaging.

Voltage, temperature and VARs can also bemonitored with the Control set for AUTO/OPERATIONS simply by rotating the ADJUSTknob. After displaying the desired readingsfor 5 seconds, the display will automaticallyrevert to the operations counter.

The Model 2000 VAR Control can monitor manysystem parameters from the primary feeder. Allof these parameters can be displayed by selectingMONITOR from the mode switch.

LINE AMPS is the total current on the line, both real and reactive. AMPS REAC is thereactive component of the total line current. Reactive amps will be displayed alongwith LD for leading, LG for lagging, RV for reverse, and UN for unity power factor.Both LINE AMPS and AMPS REAC will show LOW AMPS in the display if less than3 amps are measured. The AMPS REAC setting can be particularly helpful whenadjusting the Amps Reactive set points for VAR Control. The effect of the capacitorbank on feeder VARs can also be seen by monitoring this setting while manuallyopening and closing the capacitor bank. AMPS THD% is the Total Harmonic Distortionin the line current. KVA is Kilo Volt Amperes.

KILOWATTS are the real component of the KVA. POWER FACTOR is displayed as apercentage of unity, e.g. 90% for a 0.9 power factor. To properly display KVA, KVARand KW; the PT RATIO must be set. This is the ratio of the transformer supplying powerto the Control. For example, the ratio for a 7200V line to ground connected transformersupplying 120V to the Control would be 60 (7200 / 120 = 60).

CONTROL VOLTS is the voltage used to power the Control, typically 120 or 240V.KV is the primary voltage in kilovolts and is derived from CONTROL VOLTS x PT RATIO.KV THD% is the Total Harmonic Distortion in the line voltage. POWER FLOW DIRECTIONshows in the display as FORWARD or REVERSE. This will indicate a current sensor thatis wired backwards.

Line Amps, Amps Reactive and Voltage can also be monitored withthe Control set for AUTO/OPERATIONS simply by rotating the ADJUSTknob. After displaying the desired readings for 5 seconds, the displaywill automatically revert to the operations counter.

NEUTRAL CURRENT MONITORINGOn units equipped with optional Neutral Current monitoring, the capacitor bank neutralline is monitored. A neutral current sensor is mounted around the capacitor bank neutrallead and is connected to the Control. High neutral current is indicative of unbalanced VARloading and can be used to trip the capacitor bank off line and keep it off line until theControl is manually reset. The neutral amps are averaged over five minutes when in AUTOmode. This average is used for comparison to the set point.

The NEUTRAL SENSE OPTION works in the following manner:

1. In MANUAL MODE, monitoring of neutral amps is accomplished by selectingVOLTS MONITOR, then rotating the ADJUST knob one position in either direction.

2. In AUTO MODE, monitoring of neutral amps is accomplished by rotating theADJUST knob slowly until the display reads iA (Instantaneous Neutral Amps),and aA (5-minute Averaged Neutral Amps).

3. The neutral amps trip set point can be set from 3 to 100 amps. The setting below 3amps will disable the neutral amp trip function. The display will read disabled.

4. In AUTO mode, if the neutral amps rise above the set point, the Control will open thecapacitor bank, light the neutral trip LED, and hold the bank locked out until manuallyreset. Resetting the Control from neutral amp lockout is accomplished by rotating theMODE switch to the NEUTRAL AMPS, TRIP / RESET position.

The internal wiring connections for the neutral current sensor are shown in the diagramson page 5.

CLOCK BACK-UP BATTERYAll Capacitor Controls use a back-up battery for maintaining the internal clock settingswhen Control power is interrupted (The NoMax 2000 VAR Control uses the clock for datalogging only). The lithium battery has a 10-year life and can be replaced through thebattery access port in the front panel. If power is interrupted to a Control with a deadbattery, all time settings will be lost. When this happens, the Control will alternatelydisplay TIME ERR when in the AUTO/ OPERATIONS mode.

Only the internal clock, which is used for data logging, is dependent on the battery.All other previously logged data, front panel settings and Control programming isstored in non-volatile memory, which retains its contents indefinitely without power.

16

TROUBLESHOOTINGNoMax Capacitor Controls are sophisticated microprocessor based systems. There areno user serviceable parts inside. Any disassembly of a Control may damage componentsand expose lethal voltages. All servicing should be referred to the factory.

When the Control is first powered up, a self-test sequence is performed that tests all ofthe front panel lights. All of the LED’s flash on and off in sequence and the LCD displaysthe Control firmware revision.

If the Control is exhibiting problems, the following test procedure may be helpful fortroubleshooting. For additional assistance, contact the factory.

1. POWER ONVerify that the LCD display is showing characters and/or numbers thusindicating power to the controller. If the display is blank, measure the input voltageacross terminals Line 1 (L1) and Neutral (N) just below the front panel. If the correctinput voltage is available and the display is still blank, contact the factory for assistance.

2. VOLTS MONITOR Rotate the MODE switch to the VOLTS MONITOR position.Compare the value on the display to a calibrated digital voltmeter (DVM) readingacross terminals L1 and N. The two values should be within +/- 2 VAC. This valuetakes into account the tolerances of the Control and a typical DVM.

3. TEMPERATURE MONITOR Rotate the MODE switch to the TEMP MONITOR position.Compare the temperature on the display to a calibrated digital temperature meter(DTM). Place the temperature sensor of the DTM tight against the Control temperaturesensor; this is the gold button on the bottom of the enclosure. The measured valueshould be within +/- 3 degrees Fahrenheit (°F). This value takes into account thetolerances of the Control and a typical DTM.

4. MANUAL CLOSE AND OPEN Place the Control in manual mode by rotating theMODE switch to any position other than Auto/Operations. Use the manual toggleswitch to perform a close or open operation. The Operation Pending light will flashfor the length of time selected by the TIME DELAY setting. Once the delay time haselapsed, the Control output will energize and the appropriate LED will flash open orclosed. If the open or closed LED is on but the capacitor bank switch failed to operate,check the 15-amp front panel fuse. If the fuse is bad, replace it with a 15-amp Slo-Blo®fuse. Note: If operating from open to close, a 5-minute close inhibit will be active if5 minutes has not elapsed since the last open operation. Also, the Control cannotsense the position of the capacitor bank switches. A newly installed Control may notshow the correct switch position. Similarly, a blown fuse or a bad capacitor bankswitch can cause the Control to indicate the wrong switch position.

5. SET TIMETo verify the correct time setting, rotate the MODE switch to SET TIME. Comparethe displayed time to an accurate time source. The displayed time should be within+/- 5 min. If the two are different, reset the Control time and check the front panel battery.Remove the battery cover and pry up one end of the battery with a small screwdriver toremove. Replace the battery with a size 2/3A, 3V Lithium or equivalent. Note the properpolarity when installing. Reset the Capacitor Control to the current time and date witheither the front panel switches or the software. Note: The time is set in 5-minute incrementsvia the front panel. Follow the same procedure for the date. If the time or date cannot beset or continue to be lost when power is interrupted, contact the factory for assistance.

17

6. OPERATION SET POINTSTo verify proper operation of the set points, the recommendedprocedure is to download both the profile and setup data and examine the datawith respect to the set points. The profile data will show the Time On/Off,Close/Open Volts or VARs and Start/Stop Dates as well as collected system data.This also checks the relay outputs, (noting the rise and fall voltage values of thebank at the sampled times) Control sensors and profile memory.

7. COMMUNICATIONS PORT Place the Control in Manual mode by rotating theMODE switch to any position other than the Auto/Operations or Set Time. Usinga computer with installed NoMax software, download the profile and setupdata. While downloading the data, the Control display should show COM BUSYindicating that the RS-232 communications link is working properly. Note anymessages displayed on the computer screen during the download procedure.Follow the instructions given on the screen. If the Control is unable tocommunicate with the computer, contact the factory for assistance.

The following information regarding the front panel displays may prove helpfulin diagnosing a Control that appears to be functioning improperly.

LED INDICATORS• AUTO/OPERATIONS - Indicates the Control is in automatic mode. The Control will

open and close the bank only per the programmed settings and the toggle switchis disabled. The display indicates the total number of CLOSE operations. When theLED is off, the Control is in manual mode and the toggle switch is enabled.

• OPERATION PENDING - Flashes during the number of seconds selected byTIME DELAY for every pending OPEN or CLOSE operation.

• CLOSE - Shows the bank status as closed. A flashing LED indicates theCLOSE output is energized.

• OPEN - Shows the bank status as open. A flashing LED indicates theOPEN output is energized.

• NEUTRAL AMPS TRIP / RESET - (Optional) The capacitor bank neutral current hasexceeded the preset threshold and the bank is locked OPEN. To reset this condition,rotate the MODE switch to the NEUTRAL AMPS TRIP/RESET position.

LCD DISPLAY• AMP ERR - The current sensor is not operating properly. If this is a transient condition,

the Control will automatically reset the current sensor input and continue to operateproperly. A permanent current sensor failure can be verified with the MONITOR - LINEAMPS setting which will show LOW AMPS. If this condition is permanent, the Controlwill not perform any VAR related operations but will otherwise operate normally.

18

• COM BUSY - The Control is communicating via the RS-232 communications port.• LOW LINE - The supply voltage has dropped below its operating threshold (92V for a120V unit and 180V for a 240V unit). The Control will go into a standby mode until thevoltage recovers and will then perform a power up self-check.

• OP LIMIT - The Control has reached its daily limit of automatic close operations as set byMAX OP’S/DAY. The Control will not CLOSE automatically again during the present 24hour period. Manual CLOSE and OPEN operations can still be performed.

• REVERSE - The Control has detected current flowing in the reverse direction. If thismessage is displayed upon initial installation, the current sensor may be connectedbackwards or to a different phase than the supply or sense voltage.

• SYS ERR - The Control has detected a memory defect. The Control will stop operatingand must be returned to the factory for repair.

• TIME ERR - The Control has detected a timing error, most likely due to a dead clockback-up battery. This condition can be reset temporarily by resetting the Control’s timeand date via the front panel or via the NoMax software. Permanent repair requiresbattery replacement.

• VOLT ERR - The voltage sensor is not operating properly or the voltage being measuredhas fallen either below 100V or above 150V. If this display is due to a short-term voltagechange, the Control will reset automatically. While this condition persists, the Controlwill not perform any voltage related operations but willotherwise operate normally.

• 5MIN DLY - Will be displayed for 5 minutes following any OPEN operation. The Controlwill not perform a CLOSE operation this period.

NOMAX PROGRAMMING AND DATA ANALYSIS SOFTWAREFeaturesVersion 5 NoMax software aids in programming a NoMax Capacitor Control for capacitorbank switching and power system monitoring via a computer. The software includes thefollowing features:• Design capacitor bank control strategies in the office for future uploading to the Control.• Create and save different control strategies for different model Controls all with thesame software.

• View and analyze data downloaded from Capacitor Controls. Examine Control switchingoperations, power outages and system parameters such as voltage or VARs.

• Graph stored voltage, temperature or load current data. Zoom in on areas of interest.• Connect to a Control for real time monitoring of the Control parameters such as voltage,temperature or VARs.

• Download stored programs to update a control strategy or download a control programfrom a control back to a computer.

• Set up the Control for data logging. Program the Control to store control and systemparameters such as switching operations, voltage, temperature or VARs.

PRECAUTIONSPrecautions must be taken before connecting a computer to an installed capacitorbank control.

CAUTION! Before connecting a computer to an installed capacitor banktake the following steps:1. Ensure the Capacitor Control is properly grounded.2. Set the Control so it isnot at AUTO / OPERATIONS or SET TIME.Failure to follow these precautions may result in damage to thecomputer, unexpected capacitor bank operation or personal injury.

21

SOFTWARE INSTALLATIONHARDWARE REQUIREMENTS: NoMax software runs on Windows™ 95 or higher.The proper installation and use of this software requires a 386 or better computerwith at least 32 MB RAM and at least 20 MB of free hard disk space. The software willcommunicate with the Capacitor Control through an open serial port - either COM1or COM2. A DB-9 connection is required. The cable connecting a computer to theControl should be a straight through serial cable. The NoMax Capacitor Control isequipped with a DB-9 female connector.

Before beginning the software installation process, close or exit all other programs.The NoMax software is provided on CD. Installation will begin automatically providedthat auto-insert notification is not disabled on the computer being used. If installationdoes not begin automatically, double click the CD ROM drive in “My Computer” andrun Setup.exe from the CD.

Using the Softwarefor the first timeStart the NoMax software via the NoMaxicon or use the Windows™ Start buttonto navigate to the NoMax folder. Beforeconnecting the computer to a NoMaxControl, verify that the computer is setup for communications on the correctCOM port. COM1 is the default port in thesoftware. If necessary, change the port asshown in the graphic, starting with theCommunications drop-down menu.

IMPORTANT! If the COM port is changed, the NoMaxsoftware must be restarted for the change to take effect.

Create a Control programTo program a NoMax Capacitor Control witha computer and NoMax software, a Controlprogram must be created as shown here.

Select File, then Open. If this is the firsttime for setting up a program, select one ofthe default programs for the Control modelthat is to be programmed. For example,select 1600.ws for a Model 1600 Control. Apreviously created file may also be selected.All setup files will have a .ws extension.

After the file is opened, the name of thefile will be shown on the title bar of themain window.

22

Note that the NoMax Control front panel ADJUST knob can be disabled in the mainwindow by un-checking Manual setpoint adjustment enabled. This provides a levelof security and prevents unwanted changes to the control program in the field.

Select a Schedule. Each time schedulemust be programmed individually. Todisable a schedule, set the start date thesame as the stop date. To make a scheduleactive 24 hours per day for around theclock voltage control, set the start time thesame as the stop time. The schedules inblack lettering are active schedules, orangelettering refers to inactive schedules.

Note that negative Amp settings are usedto indicate lagging amps. Positive Ampsindicate leading Amps.

When programming a Model 2000 VARControl, select the Sensor type that will beused. For either Fisher Pierce™ or Lindsey™sensors, the sensor phase shift is automati-cally set in the software (to +90°). Bothhave a ratio of 600A/10V. If the currentsensor is on a different phase from thecontrol voltage, add or subtract 120° asrequired. For example, if the current sensoris on A-phase, and the Control is poweredfrom B-phase, enter 120° in the Phase shift box. Because settings must be entered inthe range of -180° to +180°, settings greater that 180° must be entered with a reciprocal.For example, 210° is entered as -150° (210° - 360° = -150°). Consult the manufacturer’stechnical literature for additional information regarding the current sensor. The FisherPierce™ sensor also requires the additional Cable diameter setting shown.

After entering all the desired settings,save the new file. Enter a file name andselect File, then Save. The NoMax softwareautomatically adds the .ws extension.If an existing setup file was modified,Save Asmust be selected so the originalfile is not overwritten.

To print the Active setup file, select File,then Print. To print another setup file,select File, then Open, then Print.
